commit f456767d3391e9f7d9d25a2e7241d75676dc19da upstream. Add new code to count canceled pending cluster reservations on bigalloc file systems and to reduce the cluster reservation count on all file systems using delayed allocation. This replaces old code in ext4_da_page_release_reservations that was incorrect.
